I feel like in modern English, we don't say 'one' does something, but rather, it's expressed using 'you' in the sentence without being a personal statement or piece of advice.
Would this be a reasonable translation/interpretation?
Se duerme mejor con la conciencia tranquila.
- One sleeps better with a clear conscience.
- You sleep better with a clear conscience.
The second sentence is not necesarily a personal statement. It can also be said impersonally like a general statement.
I find that when I'm speaking Spanish, I over use 'you' too much in phrases like this because the sentence structure of 'one should...' doesn't occur to me. However, I can recognize the statement is impersonal while I'm saying it.
It would be helpful to know if this is the structure I should be using in these situations.
PS. I'm not referring to passing the quizzes but more for the knowledge of how to use this better in real communication.
